I am inclined to "go dark" for a while whilst I do that, but if anyone would like to help re-write the ultimate blog entry, or help out on instrumenting more tests, please contact me offlist. Apparently there is IPv6 under test... somewhere... according to reddit. Tunnelling my ipv6 via wireguard "just worked", so there's that. There have been a few other surprises, one rather major. As much as I dislike the cgnat I don't see how starlink had any other choice, and the layer below that is hopefully capable of carrying ipv6 well.
